Correlations of hemodynamic parameters with left ventricular (LV) global longitudinal strain (GLS) stratified by ejection fraction (EF). The relationship between systemic vascular resistance index (SVRI) and LV GLS in patients with (A) EF ≥ 50% and (B) EF < 50%. The relationship between characteristic impedance (Zc) and LV GLS in patients with (C) EF ≥ 50% and (D) EF < 50%. The relationship between effective arterial elastance index (EAI) and LV GLS in patients with (E) EF ≥ 50% and (F) EF < 50%. The relationship between total arterial compliance index (TACI) and LV GLS in patients with (G) EF ≥ 50% and (H) EF < 50%
